The Innotech GenII AI REM Analogue Input Module is a remote expansion device for the Genesis range of Digital Controllers.

The module is powered by 24 V AC and provides 6 analogue inputs to be connected to field equipment. Each analogue input has a socket for an Analogue Input Signal Conditioner (AISC) which defines its input type and range selection. Analogue input resolution for the GenII AI REM is 14 bits.

The AISCs used are the same as those used on the Genesis Digital Controllers.

The GenII AI REM may be located remotely from the Genesis Digital Controller providing distributed analogue inputs for the system.

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

The GenII AI 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 GenII RMI Remote Module Interface is required. Please refer to the GenII RMI Datasheet (DS15.01) for further information.

	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.
	UL	https://www.ul.com UL marking for USA and Canada indicates that the product conforms with the safety standards laid down by Underwriters Laboratories.

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.

Inputs

6 Analogue Inputs
The Analogue Inputs require an Analogue Input Signal Conditioner (AISC) to determine the Input type (AISC’s must be ordered seperately). *NOTE: The GenII TD1, GenII D33 & GenII P20 Straps CANNOT be used with the GenII AI REM.

Communications

The cable run between the GENII AI 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.
Strictly follow the guidelines when installing the Comms wiring as outlined in the Genesis II Installation Manual.
Mount the GENII AI 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 Module. 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, a 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 Instructions for more information.
Analogue input cables should be run using twisted pair shielded cable. The shields are to be connected to terminals M, N or O.
