6.2 Extension module
Extension module can be connected to the same type of SR main machine to extend the I/O,
each extension module has 12I/8O, one SR can be connected to 5 extension module one by
one. Such as that SR-22 can be connected to 5 SR-20 to reach 74I/48O. This powerful
extension function brings you much easier to do the control system, and also lower you cost
very greatly. The I/O of extension module is divided as:
Inputs of No.01 extension module are IC0~IC7, ID0~ID3,
Inputs of No.02 extension module are E0~IE7, IF0~IF3,
Inputs of No.03 extension module are IG0~IG7, IH0~IH3,
Inputs of No.04 extension module are II0~II7, IJ0~IJ3
Inputs of No.05 extension module are IK0~IK7, IL0~IL3.
Outputs of No.01 extension module are QC0~QC7
Outputs of No.02 extension module are QE0~QE7
Outputs of No.03 extension module are QG0~QG7
Outputs of No.04 extension module are QI0~QI7
Outputs of No.05 extension module are QK0~QK7
