Publicaton 1395-RTP-5.2 - September 1997

Introduction 1-3

Specifications

The following is a listing of board specifications and features. Any

specifications pertaining directly to procedures detailed in this

manual are presented when necessary.

Digital Reference Input – This is the current source and sink input

for high common mode noise immunity with nominal 5V DC or 12V

DC interface (internal hardware configurable) and ±10 mA nominal

current source/sink requirements. A typical application utilizes a

75174 quad driver integrated circuit mounted on either an encoder

driver module (available from Allen-Bradley) or in the customer's

interface circuitry. The hardware is configured for 5V DC inputs for

RTP Unwind Drive applications.

Digital Inputs – These inputs are 24V DC nominal; 18V DC

minimum, 28V DC maximum; 10 mA nominal.

NOTE: A separate panel mounted 120V AC, I/O module is used as

an interface to satisfy the 120V AC voltage rating.

Discrete Outputs – These outputs are 24V DC nominal; current

sourcing type driver; diode clamped for inductive load; 18V DC

minimum, 28V DC maximum; 1.5V DC saturation, 100 mA

maximum load.

NOTE: A separate panel mounted 120V AC, I/O module is used as

an interface to satisfy the 120V AC voltage rating.

Analog Inputs – These inputs are 0 to ±10V DC, differential input

impedance – Differential > 1Meg Ohm; 20K Ohms (single ended to

analog common).

Analog Outputs – These outputs are -10V DC to +10V DC, 2.5 mA

maximum. Output impedance – 200 Ohms.

Power Supply – The power supply voltage is +10V DC, 4 mA

maximum -10V DC, 4mA maximum Firmware Version – The

firmware version is 3.xx or 4.xx.
