Reference Adapter for RTP Applications User Manual

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.
