MMTCP8AI/I ISO – 8 Current Input Module Fully Isolated
The MMTCP8AI/I ISO module is a 8 channel isolated current input module. The module uses differential inputs to reduce effects of electrical noise and mains pickup. The current inputs are isolated from the logic and from each other.
The current input can be represented in a number of formats according to the type which is setup by writing a value to the Type register. The value is obtained from the table below.
The standard setting for the MMTCP8AI/I ISO module is 0 - 20mA input current which represents an output value of 0 - 4095 (12 bits) in the corresponding Modbus register. 4 mA would give a reading of 819 ± 1LSB.
The module can also be configured for a 0 – 20.000mA input range or +/- 20.000mA input.
