L Series High Performance Process Limit Controllers
Brand: Future Design ControlsThe L22, L62 & L42 are FM approved limit controller that can be configured either as a high limit or as a low limit controller by the user.
These limit controllers are powered by an 11-26 or 90-250 VDC / VAC supply, incorporating a 2 Amp relay output as a standard.
The second output can be used as an alarm. Both outputs can be selected as a 5VDC or 14VDC logic output to drive an external device.
The limit controllers can be incorporated with two event inputs, up to 3 alarm outputs, RS-485 communication, retransmission voltage or current output optionally.
The limit controllers are fully programmable for linear current, linear voltage, Pt100 and thermocouple types J, K, T, E, B, R, S, N, L, U, P, C, and D.
The input signal is digitized by using an 18-bit A to D converter. Its fast-sampling rate allows the limit controller to protect fast processes.
