Assembly 8-channel Simplex/Duplex
Apply a minimum tightening torque of 0.5 N•m (0.37 lb•ft) to the terminal
screws.
The 24V DC field voltages VFIELD 1 and VFIELD 2, used by the output
module for the output field voltages, are connected at the terminal blocks and fed
via two replaceable 10 A fuses, F1 and F2. These fuses give protection for the
output module against field faults. Field OV (VFIELD RTN) is also routed from
the output module connectors to the terminal block.
