Trip relay
PR ELECTRONICS

Trip amplifiers are a common part of safety systems in e.g. the maritime industry in which supervision of e.g. oil-fired steam boilers. Thus, the trip amplifiers observe the process, control the pumps and burner due to water level and steam pressure and sound the alarm at e.g. an inappropriate high or low water level. Naturally, boiler control is a safety question, and thus, the trip amplifiers must be very reliable and precise.

The comprehensive range of trip amplifiers from PR electronics:
2200-series

The 2200-series for mounting in DIN rail with 11-pole socket consists of one single and one dual trip amplifier covering mA, mV, A, Hz, and PT 100 temperature input as well as relay, mA and V output. Additionally, the modules offer increasing, decreasing, hold and/or window relay functions. Depending on the module the configuration is carried out by means of front keys or knobs.
