This cartridge of 4 relay outputs (with NO contact), 2 opto-isolated digital inputs (for voltage-free contacts) and 1 opto-isolated analogue output is an option for SC-A CRT indicators family that can be placed in the 3rd and 4th slots (from the right) of the rear housing of the device.
Its analogue output allows to turn the weight signal into either a 16-bits output ranged [4-20mA] or into a voltage output ranged [0-10V], selectable by jumper, to integrate the weight signal into a PLC.
