Figure 2.47 PPC-2040 Connection to TB50
NOTE! To avoid confusing the SCSI cables during servicing,
label each end of each cable and each terminal board
with the address of the module to which it should be
connected.
TB50 Connections
Connect digital inputs and digital outputs for control signals,
alarms, and digital field I/O to the TB50. The PPC-2040 Digital
I/O Module supports up to 32 digital inputs and outputs and up
to two single-ended counter/frequency inputs. Counter inputs
may be single-phase or quadrature. Connecting one single-
phase counter or frequency signal uses one digital input.
Connecting one quadrature input requires two digital inputs.
Table 2.21 on page 63 shows the TB50 pinout when used with
the PPC-2040.
Use 14 to 22 AWG wire. When making connections, tighten to
0.5 to 0.6 Nm, or 4.5 to 5.4 inch-pound.
