PID Controllers

The iDR Series signal conditioners and PID controllers for DIN-rail mounting feature an Ethernet option that connects the instruments directly to a LAN and can serve Web pages over the Internet.

The devices are easily configured with a handheld programmer or from a PC with an Ethernet, RS-232, or RS-485 connection. The universal signal input covers 10 thermocouples, 100 and 1,000 Ω RTDs with two, three, or four-wire connections, process (dc) voltage, current, and strain-gage inputs. Optional outputs include Form C SPDT relays, SSRs, dc pulse, programmable isolated or nonisolated analog voltage and current.
