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

The module is powered by 24VAC and provides 5 opto isolated digital inputs to sense pulsed signals from field equipment. The voltage detection range is 12 to 24 V DC.

The GenII PI REM may be located remotely from the Genesis Controller providing distributed digital pulse inputs for the system.

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

The GenII PI 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.

The GenII PI REM detects pulses with a minimum on time of greater than 20ms, with a minimum off time of 20ms, which gives a maximum of 25 pulses per second.
5 Optically isolated digital pulse inputs
LED indication of input status.
Remote sensing and control of I/O points, up to 500m from the Genesis II Controllers.
Housed in a low profile DIN rail-mounted enclosure.
RS485 interconnection between modules.
Galvanic Isolation for communications to prevent grounding problems.
JUMPER selectable Address Number (1-15).
Wiring Diagrams for modules Generated by Gen2Config Software.
LED indication of network traffic assists network setup & debugging.

Expands Genesis Digital Controller I/O capabilities by providing 5 opto isolated digital pulse inputs allowing distributed data acquisition via RS485. Typical applications include accumulating reading from sources such as a Kilowatt hour meter.

Application Notes
A Genesis Controller must have version 4.1 firmware installed to support Pulse Inputs REM Modules. Version 4.1 Config Software must be used to configure a Genesis Digital Controller that has Pulse Input REM Modules connected to it.

A Genesis Digital Controller can have up to 15 GenII PI 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.

Inputs:

0 V OFF
12-24V DC ON
(Supplied by Class 2 power source)

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 electrically 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.
