Sep 22, 2009
The EV6421M from Celsum Technologies is a versatile, general purpose, DIN-Rail or surface-mounting temperature controller.
It allows a range of input signals, has a built-in display, an on/off control action and two programmable alarms.
The EV6421M allows a wide range of input signals, has a built-in display, has an on/off control action and has two programmable alarms
It is available in 115 and 230V mains-supply versions and has an alarm buzzer that can be programmed to activate or not in an alarm condition.
Permissible inputs are from PTC thermistors, NTC thermistors, Type J thermocouples, Type K thermocouples, two- or three-wire PT100 or PT1000 platinum resistors, Ni120 sensors, or 0-10V and 2-10V voltage signals.
The built-in display may be set to display temperatures in C or F, and the resolution of the display, depending on inputs is 0.1C, 1C or 1F.
Each of the dual alarms may be set as high or low, and absolute or relative.
The output relay will handle AC loads of up to 10A and may be wired Normally Open (NO) or Normally Closed (NC).
There is a multipurpose digital input (5V, 1mA, NO/NC), the action of which may be programmed.
Programming is effected manually via the integral, lockable keypad.
The EV6421M is IP54 protected and has a body of self-extinguishing grey plastic.
The working temperature range is 0 to 55C (32 to 131F) and the working humidity range is 10 to 90 per cent RH without condensate.
Connection to the module is via screw terminals and its size is three DIN modules or 53mm (2.1in) (W), 90mm (3.6in) (H), and 61mm (2.4in) (D).
