7-18 Specifications
Remote Control (GPI) Interface
Configuration: Eight (8) inputs, opto-isolated and floating.
Voltage: 6–15V AC or DC, momentary or continuous. +12VDC provided to facilitate use
with contact closure.
Connector: DB–25 male, EMI-suppressed.
Control: User-programmable for any eight of user presets, factory presets, bypass, test tone, stereo or mono
modes, analog input, digital input.
Filtering: RFI filtered.
Tally Outputs
Circuit Configuration: Two NPN open-collector outputs.
Voltage: +15 volts maximum. Do not apply negative voltage. When driving a relay or other inductive load, connect
a diode in reverse polarity across the relay coil to protect the driver transistors from reverse voltage caused by
inductive kickback.
Current: 30 mA maximum
Indications: Tally outputs can be programmed to indicate a number of different operational and fault conditions,
including Input: Analog, Input: Digital, Analog Input Silent, AES In- put Silent, and AES Input Error.
Power
Voltage: 80–264 VAC, 50–60 Hz, <65 VA.
Connectors: Two (2) IEC, EMI-suppressed. Detachable 3-wire power cord supplied.
Fuse: T2A Quick Acting HBC, mounted on the power supply circuit board.
Grounding: In order to meet EMI standards, circuit ground is hard-wired to chassis ground.
Safety Standards: ETL listed to UL standards, CE marked.
Environmental
Operating Temperature: 32° to 122° F / 0° to 50° C for all operating voltage ranges.
Humidity: 0–95% RH, non-condensing.
