Option 27: 8-Channel High Drive

C.11.1

General Description

Option 27 provides eight independent, IRIG-B buffered outputs, each capable of driving multiple
loads. Outputs are short circuit and surge protected. Each output is individually configurable for
either modulated or unmodulated IRIG-B signals via jumper settings as illustrated in Figure C.8.
C.11.2 Specifications
Output Selection

Eight (8).
4.5 Vpp with 20-Ohm source impedance; each channel
will drive a 50-Ohm load to 3 Vpp minimum; requires
Option 92 in Model 1093A/B/C.
+5-V open-circuit; +4 V minimum at 250-mA
load current each channel will drive 25 Schweitzer
SEL-3xx (in parallel) or 50 SEL-2xx (in series/parallel)
relays at 10 mA per relay.
No Limit: will drive a short circuit.
250-mA peak current; pulse-by-pulse shutdown if load
current exceeds internal limit (self-resetting).
