Analog Output Modules
Acromag’s ES2171 and ES2172 analog output modules provide 16-bit Ethernet-to-voltage or current conversion for control of up to 16 industrial devices. The modules accept Modbus TCP/IP, UDP/IP and i2o peer-to-peer network inputs, and provide high-resolution analog outputs to drive displays, indicators, chart recorders, positioners and actuators. An aluminum enclosure resists 50G shock and 5G vibration. The units are designed to mount on machinery, DIN rails or walls. The industrial-grade specs feature -40 to 75 degrees Celsius operating temperatures.
The Model 4683-TTM-3F RS-485 network repeater from Acromag is designed for use with Johnson Controls N2 or BACnet MS/TP bus control systems. The device drives up to 32 RS-485 devices and isolates and boosts signals up to 4,000 feet. Electrical surge protection with 1,500-volt AC isolation shields the host computer from destructive noise spikes and other transient signals. The product has multiple LEDs and field-selectable EOLN terminations. The device is available in 24-, 115- and 230-volt AC power models.
