)
To connect wiring to the terminal block,
insert a screw driver into the orange tab and
press down (figure 11), opening the
terminal. Insert the wire into the terminal
and release the orange tab, clamping the
wire in the terminal.

Check the connection by GENTLY tugging
the wire to ensure it is locked in.
NOTE: 14
AWG wire can be used if it is carefully
stripped (see figure 12).

A 4 to 20mA output signal is provided by
the Model S216A Hydrogen Sulfide Gas
Enhanced Smart Sensor and can be sent up
to 9000 feet (2740 meters) to a General
Monitors readout/relay display module,
industrial analog to digital converter,
computer based monitor, PLC, DCS, etc.
See the Appendix (section 5.1.3) for cable
length specifications. The 4 to 20mA signal
provides for a control room or other location
remote to the Model S216A to display
operation and alarm conditions. To connect
the 4 to 20mA output signal with another
unit, connect the white wire to TB1, position
1 (CE Mark units - TB4, position 1), labeled
4-20 mA OUT. For making output signal
connections to display devices, refer to the
specific manual for that device (figure 13).

If a device other than a General Monitors
readout/relay display module is being used,
the commons, COM, of both systems must
be connected together. The Model S216A
Hydrogen Sulfide Gas Enhanced Smart
Sensor operates from a nominal supply of
+24 VDC. Primary DC power must be
provided by the customer unless one of the
following General Monitors Modules is
being used with the Model S216A:
l
DT200 Readout/Relay Display Module
l
DT210 Readout/Relay Display Module
with Power Supply & Relay Module
l
DT230 Readout/Relay Display Module
l
TA202A Trip Amplifier Module with a
