P Series Ramp Soak Profile Single Loop Control


from $245 List


The FDC-P Series of controllers, the FDC-P41 1/4 DIN and FDC-P91 1/16 DIN, with up to 9 Profiles (up to 64 segments/profile) and up to 5 outputs set new standards for single loop Profile controls. Packed with performance and features meeting simple or complicated OEM applications, the P Series provides an unrivaled value.


Exceptionally easy to use, the P Series offers up to 9 Profiles with up to 64 segments per program, maximum of 4 control outputs, configurable Event input, PID Selection by Segment or Event input, PV/SP Retransmission (15-bit), serial Modbus RTU communication option, fast scan rate (5 scans/second), user friendly prompts, PC Configuration port and a Home Page feature that make it the right choice for a Profile


The P Series offers a full range of universal high resolution (18 bit) inputs; T/C, RTD and linear mA/VDC inputs. Power requirement of either 90-250 VAC or optional 11-26 VAC/VDC allows the P Series to be used virtually anywhere.
