Terminal Connections
The terminal blocks (TB) are located inside the housing and can be accessed by removing the
cover. A label on the inside of the housing cover provides details of all the terminal
connections.
WARNING:
Do not c24 VDC to TB1. Damage to the electronics or sensor may
result.
It is recommended that a minimum three-wire shielded cable be used for making the power
and 0-20mA Output connection on TB2 of the S4000CH. It is also recommended that separate
two-wire shielded twisted pair
cables be used for making the Modbus connections. The spring
type terminal block accepts 14 AWG to 20 AWG and the screw type terminal block accepts 12
AWG to 18 AWG stranded or solid wire. Each wire should be stripped before wiring the
S4000CH intelligent sensor. To connect wiring to the spring type terminal block, insert a
screwdriver into the orange tab and press down (Figure 5), opening the terminal. Insert the wire
into the terminal and release the orange tab, clamping the wire in the terminal. Check the hold
of the wire by GENTLY tugging it to ensure it is locked in.
