Adds eight independent, buffered outputs, each capable of driving multiple loads. Available on the Models 1201B/C.
Option E03 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.
Each output is jumper selectable for either a Modulated or Unmodulated signal.
Number of Channels: Eight (8).
Modulated: 4.5 Vpp with 20-Ohm source impedance; each channel will drive a 50-Ohm load to 3 Vpp minimum.
Unmodulated: + 5-V open-circuit; + 4 V minimum at 250-mA load 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.
Maximum Load (per driver):
Modulated: No Limit: will drive a short circuit.
Unmodulated: 250 mA peak current; pulse-by-pulse shutdown if load current exceeds internal limit (self-resetting).
