7706

All-in-One I/O Module 7706 CAPABILITIES Channels 1–20: Multiplex one of 20 2-pole or one of 10 4-pole signals into DMM. Channels 21–25 are referenced to chassis ground. Channels 21–22: 16 Digital Outputs. Channels 23–24: Analog Voltage Output (2). Channels 25: Totalize Input. Use with Integra Series mainframes: 2700, 2701, 2750 • 16 channels of digital output • 2 analog outputs (±12V, 5mA) • 300V, 1A capacity; 60W, 125VA maximum INPUTS Maximum Signal Level (Channels 1–20): 300V DC or rms, 1A switched, 60W, 125VA maximum. Contact Life (typ.): >105 operations at max. signal level; >108 operations no load 1 . • Configurable as two independent banks of multiplexers 1 • Relay closures stored in onboard memory The Model 7706 plug-in module offers 20 channels of 2-pole or 10 channels of 4-pole multiplexer switching with automatic CJC, as well as two analog output channels, 16 digital outputs, and one event counter/totalizer. The event ­counter/ totalizer can be used to monitor and control system components, such as fixtures, limit switches, pass/fail indicators, external voltage sources, loads, door closures, revolutions, etc., while performing mixed signal measurements. The Model 7706 is ideal for RTD, thermistor, and thermocouple temperature applications.
