The MCR-2SP/UI dual setpoint module is designed specifically for process control applications. The flexibility of either internal or external alarm setpoint adjustments and DIN-rail mounting, creates many installation possibilities.
The MCR-2SP/UI accepts either 0(4)-20 mA or 0-10 V dc analog input signals. DIP switch selectable variables include a 1% setpoint hysteresis and normally open/ normally closed selectable alarm relay action.
The two digit, decade switches located on the top of the module allow for easy adjustment of the alarm setpoints. A corresponding yellow LED indicates the status of the relay contact for each setpoint.
Each setpoint has a 0-4 seconds on-delay timer adjustment. This on-delay adjustment is very useful in applications involving turbulence. The time delay will eliminate relay chatter caused by any analog level process signal's quick fluctuation. This delay can eliminate nuisance relay tripping or chattering.
The MCR-2SP/UI contains a +5% zero and span adjustment for fine calibration of the setpoint trip points.
The two setpoint relays are rated at 3A/250 V ac/dc, and utilize silver cadmium oxide contacts.
External Analog Setpoint Function
The MCR-2SP/UI can accept up to two external voltage or current setpoint
inputs. By applying an external voltage or current, an additive effect is
created to the threshold circuit. For example, if the MCR-2SP/UI is configured
for a 0-10 Vdc analog input signal, and setpoint (1) threshold decade switch is
set at 60 (60%) (a 6 volt relay setpoint), by introducing a 1 V dc signal, the
effective alarm threshold is now 70% or 7 Vdc.
