TC562 Modem Unit – (Westermo MD-12DC)
Description
The TC562 Short Distance Modem unit can be used both for point-to-point
communication and for communication over a distance between pieces of
equipment or units, for example a computer and printer or a robotic device. ABB
recommends their use when the distance between units/equipment exceeds 15m.
For further details refer to the manufacturer’s documentation (Westermo).
Using a modem allows distances between pieces of equipment to be as much as
18000m, and, depending on the distance, can provide a data transmission speed of
up to 38400bit/s. The modems are manufactured for simple mounting onto a
standard 35mm DIN-rail.
Transfer between modems takes place along two twisted pair cables, one at full or
half duplex and the other at simplex. The transfer distance is fully dependent on
Mounting spacing W mm 10mm (0.4")
Mounting spacing H mm 25mm (1.0")
Weight (lbs) 800g (1.8lb)
