IGWiPS200-1
Control Room
At the control room, there is one master transceiver and complementing I/O: one analog output module, and one
digital output module. The total current requirement is 287 mA [75 mA +100 mA + 32 mA + (4 x 20 mA)].

USER SUPPLIED MATERIALS
A partial list of the materials the user must furnish is provided below. Additional materials may be needed,
depending upon peripheral and accessory equipment and the particular installation.
1. DIN rail(s), mounting hardware, and enclosure(s) appropriate to the environment and hazardous area
certification
2. Signal and power wiring and appropriate tools for wire preparation (e.g. wire cutters and strippers)
3. Conduit tubing, adapters, and outlet boxes and appropriate tools for cutting and routing conduit
4. Circuit protection devices (e.g. fuses, circuit breakers, on-off switches)
Electrostatic Discharge
Semiconductor devices must be protected from electrostatic discharge. A properly grounded conductive
anti-static wrist strap must be worn whenever a circuit board assembly is handled or touched. A service
kit with a wrist strap and static dissipative mat is available from most electronic parts supply companies.
I/O MODULE CONFIGURATION SWITCH SELECTIONS
Configure the following modules before mounting on the DIN rail.
4 Field settable switches are provided module
configuration. Default settings are provided.
• 4-Channel Analog Output Module (See Figure 13 on page 23 and paragraph A below.)
• 8-Channel Digital Output Module (See Figure 15 on page 24 and paragraph A below.)
• Combination Input/Output Module (See Figure 16 on page 25 and paragraph A below.)
• 2-Channel Pulse Input Module (See Figure 17 on page 26 and paragraph B below.)
• 2-Channel Pulse Output Module (See Figure 18 on page 26 and paragraph B below.)
4 A module may be configured after installation. However, access to switches may be impeded by adjacent modules.
