Z-10-D-IN is a module with 10 digital inputs, 16 Vdc self-powered common negative and removable terminals section 2.5 mm. Unlike Rev. Hw1, this module includes 10 inputs with a 32-bit totalizer with a maximum frequency of 2.5 kHz. Among the functions of the Z-10-D-IN are the measurement of: frequency, period, T(ON) and T(OFF) for all inputs and the possibility to set the totalizers for counting forward or backward with overflow indication for each totalizer. ON-LINE configuration possible. The use of an USB/RS485 converter with ModBUS RTU protocol is mandatory for PC programming.
