The Innotech GenII DO REM Relay Output Module is an expansion device for the Genesis range of Digital Controllers.

The module is powered by 24VAC and provides 5 relay outputs to control or switch field equipment. The relays have normally open contacts than can handle up to 2 amps at 24V AC.

The GenII DO REM may be located remotely from the Genesis Digital Controller providing distributed relay outputs for the system.

The GenII DO REM is configured and programmed via the Genesis Controller.

The GenII DO REM communicates with the Genesis Controller via the REM Comms port. The remote link uses RS-485 at a baud rate of 38400. For pre-Version 5 controllers, a Gen II RMI Remote Module Interface is required. Please refer to DS15.01 for further information.

Expands Genesis Digital Controller I/O capabilities by providing 5 Relay Outputs allowing distributed control via RS485.
Designed to operate as pilot relays. Large currents should be switched using additional high current relays/contactors.

Application Notes
A Genesis Controller must have Version 4 firmware installed to support REM Modules. Version 4 Config Software must be used to configure a Genesis Digital Controller that has REM Modules connected to it.

A Genesis Digital Controller can have up to 15 GenII DOM REM Modules* connected to it via the REM comms bus.

For detailed connection information to the pre version 5 Genesis Digital Controller Family, please refer to Innotech Cabling Manual (.pdf 1.54MB).

	CE	https://europa.eu/youreurope/business/product/ce-mark/index_en.htm The CE label is a European marking for products to indicate conformity with the electromagnetic compatibility and health and safety requirements set out in European Union.
	FCC	https://www.fcc.gov FCC marking indicates that the product conforms with the regulations of the U.S. Federal Communications Commission (FCC) for microprocessor-based equipment.
	RCM	https://www.acma.gov.au The RCM compliance mark indicates that a device complies with applicable radiocommunication and electrical safety standards.

Power Supply

Voltage: 24 volts AC ±10% @ 50/60Hz.
Power Consumption: 4VA max.

The operating voltage must meet the requirements of Safety Extra Low Voltage (SELV) to EN60730. The transformer used must be a Class 2 safety transfomer that has the energy and voltage limiting characteritics as described in the National Electrical Code, ANSI/NFPA70. It must also be sized and fused in compliance with local safety regulations.

Outputs

2Amps @ 24VAC relays Normally Open contacts. (Supplied by Class 2 Transformer.)

Terminal Identification

1 = 24V AC Supply.
2 = 0V AC Supply.
3 = Earth.

NOTE - Terminal 3 is for the protection of the Comms circuitry and must be connected to a good electrical bonded Earth. This may be the Earth bus bar of the switchboard or the point that connects the chassis of the equipment the Module is in, to electrical Earth. This point should not be tied to terminal 2.

COMMS Connection

SHLD 1	=	Shield from incoming Comms Cable.
+	=	RS 485 (+) signal.
-	=	RS 485 (-) signal.
SHLD 2	=	Shield from outgoing Comms Cable.

I/O Terminal Connections

A = N/O Relay 1.
B = Comm Relay 1.
C = N/O Relay 2.
D = Comm Relay 2.
E = N/O Relay 3.
F = Comm Relay 3.
G = N/O Relay 4.
H = Comm Relay 4.

Temperature Ratings

Storage 0 to 50°C non-condensing.
Operating 0 to 40°C non-condensing.

Enclosure
The GenII REM Modules are housed in rectangular cases made from flame retardant polycarbonate/ABS plastic listed under UL94.

Colour: Grey.
Mounting: DIN rail mounted.

Installation

The Cable run between the GenII DO REM and the GenII RMI should not exceed 500 metres. The Comms wiring requires cable especially suited for RS485. Other shielded cable is not suitable and may cause spasmodic Comms failures.
The GenII REM Modules should be mounted on DIN Rail in cabinets approved for switchgear or industrial control equipment.
Strictly follow the guidelines when installing the Comms wiring as outlined in the Genesis II Installation Manual.
Mount the GenII DO REM in a dry and clean location free of excess vibration.
There are four jumpers located in a row on the upper section of the GenII REM Modules. These are labelled A0, A1, A2 and A3. These set the address of the GenII REM Modules. Directions for setting the address are shown in the wiring diagram Generated by the Gen2Config software.

*Note:If for some reason, an address for a module needs to be changed, the unit must be powered down before the jumpers are altered. Anti-static precautions should be taken when changing addresses or adding or removing cabling from the terminals.

Wiring

The cable used for RS485 Comms must be shielded single twisted pair, 120 ohms character impedence, 36 to 45pF per metre capacitance between conductors.
The Comms cable must be organised as a bus topology. That is, starting at one end, devices are connected to it until the other end of the cable is reached. No “stubs” are allowed. To connect a device to the cable, as cut is made in the cable at the point where the device is to be situated along it. Then, the two new ends of the cable are wired into the device. The shields from the two new ends are then terminated into the terminals marked SHLD1 and SHLD2 respectively. Refer to the Genesis System Network Installation Instruction for more information.
