Analog and digital input/output modules for control and building systems

DOLD I/O modules link a system's field signals to its control. Input modules acquire signals from limit switches, push buttons, sensors and similar devices, while output modules switch the signals that drive the controlled equipment. Both analog and digital versions are offered, and they are used mainly in control engineering and building technology.

Two Modbus RTU modules make up the current range. Both are 22.5 mm wide, built to IEC/EN 61131-2, and set to their Modbus address and baud rate with three potentiometers. The UG 9460 is the digital version, with 8 DC 24 V inputs, 4 relay outputs (three rated 8 A and one 16 A) and 15 status LEDs. The UG 9461 handles analog signals, with 2 configurable inputs for 0 to 10 V or 0 to 20 mA, 2 type K thermocouple inputs, 4 inputs for Pt1000 sensors and 2 analog outputs of 0 to 10 V.
