Chapter 2: Functional Description
The Model RB-24 is a twenty-four channel electromechanical relay output accessory card. On-
board amplifiers allow the relays to be driven by any 24-bit group of any of our PCDIO Series
digital I/O card or from other manufacturer’s LSTTL or NMOS/CMOS-compatible digital output
cards that use 37 or 50-pin connections compatible with the pin connections listed later in this
manual. When an input bit is high, the associated relay is energized and a red LED associated with
each relay glows when that relay is actuated.
SPDT Form C relays are standard but DPDT Form C relays are an available option. The relays
used are UL-recognized, non-latching, polarized units designed to FCC Part 68 isolation require-
ments and can switch up to three amperes current into a resistive load at voltages up to 120 VAC
(rms).
The card is normally powered by +5 VDC external power but an option is available for 115 VAC,
60 Hz external power. In both cases, screw terminals are provided for termination of input power
connections.
As mentioned earlier, either card may be interfaced to any 24-bit port of PCDIO Series card. Relay
numbers and corresponding port-bit assignments are as follows:
