The Derell C series smart relay has a wide range of features. Its PC-based graphical editor, Derell C Editor, is free and can be used for programming, simulation, and program transfer. The relay has 256 lines, 5 contact columns, and 1 output column, with a rising/falling edge feature for contacts. It also has up to 28 digital inputs with filter features and up to 20 digital outputs.
The Derell C series smart relay has 32 time relays with 11 modes and 9 selectable times, as well as 2 time relay tickers ("Event Counting"). It has 32 counters (16-bit, forward/backward selectable) and 32 counter comparators (offset). There are also 2 fast counters and 2 state machines with internal time relays.
The relay has 3 front panel F-buttons with filter features, 48 auxiliary relays, and 16 analog comparators with hysteresis. It has up to 4 0-10V analog inputs and up to 2 PTC temperature sensor inputs. It has 32 current screens (with internal time relays) with 4 lower screens and 4 startup screens.
The relay also has a 3-level password-protected menu system with 4 password contacts and 4 configuration contacts. It has a real-time clock (optional) and weekly/yearly alarms (with real-time clock). It has an RS-485 output for expansion module connections and can be connected to a MODBUS RTU client (master) via Derell DLC Modbus. Its scan time is less than 10ms, and it has a 2x16 character backlit LCD screen.
The relay can be powered by 18-32VDC or 100-240VAC and has an 18VDC auxiliary power output for digital inputs. The Derell C series smart relay is a powerful tool with many useful features for a wide range of applications.
