AC Input Module (ACI)
The ACI is a non-intrinsically safe module that has 12
identical optically isolated AC input channels that can be
used for dispenser hook isolation, vapor processor input,
or as generic AC inputs. The TS-550 evo consoles can
handle a total of 36 AC inputs or up to three AC Input
Modules in one system.
AC Input Module Specifications
Number of Channels: 12 optically isolated
Input Voltage Rating: 110 – 240 VAC
Input Current: 7 mA RMS
Dispenser Hook Signals
The TS-550 evo system requires that the dispenser hook
signal from every dispenser on site be wired into the
console’s AC Input Module. When making the connection
for the hook signals to the AC Input Module, refer to the
following diagram and use these guidelines:
• If there are two hooks per dispenser: wire the two hooks
from Dispenser 1 to AC input channels 1 & 2, the hooks
from Dispenser 2 to AC channels 3 & 4, etc..
• If there are three hooks per dispenser, then wire the
three hooks of Dispenser 1 to the AC input channels 1,
2, 3 and so forth.

4-20mA EXP Analog Input Module (420EXP)
The 420EXP has 8 identical channels for loop powered
non-IS sensors with a 4-20 mA interface. The TS-550
evo series can support up to 24 inputs (3 modules total
including 420IB models with 8 inputs each) depending on
available space in your console. The 420EXP will most
likely be used with explosion proof version of the line leak
pressure transducers at the sites where IS wiring is not
available. It can also be used with other 4-20 mA sensors
located in non-hazardous area.
EXP Analog Input Module Specifications
Number of Channels: 8
Loop Power 24 Volts
Internal Resistance 350 ohms
Note: Components located in the hazardous area must be
an explosion proof version and wiring must be enclosed in
explosion proof conduits.
