Figure 52 – 16 channel Analog Output Wiring Diagram
DC Input Module Wiring
The DC Input Module has sixteen inputs, in two groups of eight inputs per group. The groups are isolated
from each other; inputs are non-isolated within each group. An example of Digital Input Module wiring is
shown in Figure 53. Specifications for this module and for other modules are given in the Specifications
manual.
Shield Grounding
Shields must be grounded as described under Shield Grounding at the beginning of this section.
Common Terminals
Two common terminals are provided for each group of eight inputs. Terminals 9 and 10 are connected in
the input module, and terminals 11 and 12 are connected in the module.
Jumper Comb
A two-position jumper comb is available (as an option, for barrier-style terminal blocks only) for
connecting digital common wiring (at terminals 9 and 11 or 10 and 12). See Figure 54.
Hazardous voltages exist at terminal blocks.
Using switches at field devices disconnect the field wiring from power sources before servicing.
Failure to comply with these instructions could result in death or serious injury.
32 point DC Input Module Wiring
The 32-point DC Digital Input module (Figure 55) provides two groups of 16 inputs, each with a pair of
terminals for connection to common. DC power applied between the common terminal and an input cause
the input to turn ON. A green LED on the module provides indication of an ON state. Logic in the
controller allows the state to be inverted when necessary.
Requires Low Voltage Euro style 36-terminal terminal block.

AC Input Module Wiring
The AC Input Module has sixteen inputs. An example of AC Input Module wiring is shown in Figure 56.
Specifications for this module and for other modules are given in the Specifications section of this manual.

Common Terminals
Two common terminals are provided for each group of eight inputs. Terminals 9 and 10 are connected in
the input module, and terminals 11 and 12 are connected in the module.
Jumper Comb
An optional two-position jumper comb is available as an option (for barrier style terminal blocks only) for
connecting digital common wiring at terminals 9 and 11 or terminals 10 and 12. See Figure 57.
Hazardous voltages exist at terminal blocks.
Using switches at field devices, disconnect the field wiring from power sources before servicing.
Failure to comply with these instructions could result in death or serious injury.
AC/DC Isolated Input Module Wiring
The AC/DC Input Module has sixteen isolated inputs. An example of AC Input and DC input Module
wiring is shown in Figure 54. Specifications for this module and for other modules are given in the
Specifications manual.
Requires Low Voltage Euro style 36-terminal terminal block.
Isolation
Inputs must be powered from external voltage sources. Inputs are isolated from each other and from
controller power.
Contact Input Module Wiring
The Contact Input Module has sixteen inputs in one group. An example of Contact Input wiring is shown
in Figure 59. SIL applications require an external blocking diode used to insure inputs are protected from
ground faults. See HC900 Process & Safety Controller Safety Manual for additional details.
Specifications for the Contact Input Module and other modules are given in the Specifications manual.
Internally Powered Input Channels
The Contact Input Module provides voltage to the field contacts.
CAUTION
Do not apply any external power to the field device or to the input terminals. Doing so
could damage the module.
Common terminals
Four common terminals are provided for the 16 inputs. Terminals 9, 10, 11, and 12 are connected in the
Contact Input module.
Hazardous voltages exist at terminal blocks.
Using switches at field devices disconnect the field wiring from power sources before servicing.
Failure to comply with these instructions could result in death or serious injury.
