Functional Description

• The module provides 16 point-isolated voltage detection circuits for contact sensing.
• It senses voltages across relay contacts, fuses, switches, and other contact types.
• It uses an IS200SDII terminal board plus a PDII I/O pack.
• Each channel accepts 48 V dc, 125 V dc, 115 V ac rms, or 230 V ac rms.
• Three terminals exist for each contact input channel.
• Pluggable Euro-style box-type terminal blocks simplify field wiring.
• A connector accepts different WDII option boards for system wetting.
• All 16 channels stay point-isolated when you use PDII with SDII only.

Operation Details

• The sensing circuit converts voltage at the TB input into an isolated digital signal.
• Firmware calculates the voltage present at the TB input.
• It declares the contact status as on or off based on voltage presence.
• Each input stays isolated from the others for reliable signal separation.
• All inputs are point-isolated and system-isolated without an option board.
• With WDIIH1, channels support system wetting at 24 V dc or AC rms levels.
• AC frequency range for 50 Hz and 60 Hz is ±3 Hz.
• Removing the channel fuse allows use as a point-isolated signal path.

WDII Option Board Compatibility

• WDIIH1: Supports system wetting with 24 V dc, 115 V ac rms, or 230 V ac rms across all 16 channels.
• WDIIH2: Supports system wetting with 48 V dc across all 16 channels.
• WDIIH3: Supports system wetting with 125 V dc only; all channels are group-isolated.
• Each channel can be individually configured as point-isolated on WDIIH1 and WDIIH2.
• A mix of point isolation and group isolation is possible on WDIIH1 and WDIIH2.
• WDII boards include an isolated voltage detector circuit to monitor wetting voltage.
• WDIIH boards offer field line fault monitoring with one or two field resistors.
• PDII can detect open field wiring or an open fuse on WDII with a parallel resistor.

Group Isolated Input Signals

• Contact input channels receive wetting voltage through a WDII option board.
• WDIIH1A provides 115 V/240 V ac rms, 50/60 Hz, and 24 V dc wetting voltage.
• Individual fuses exist in each supply line for protection.
• Wetting voltage connects through JE1 or JE2 parallel connectors.
• Connect pin 1 of JE1 to the positive and pin 3 to the negative.
• Do not reverse polarity at JE1 or JE2.
• Group isolation replaces point isolation when a WDII board connects.
• The system wetting voltage then comes through the WDII board.

Installation Guide

• Mount the IS230SDIIH1A on a standard DIN rail.
• Connect field wiring to the pluggable Euro-style box-type terminal blocks.
• Use three terminals per contact input channel for proper wiring.
• Attach the PDII I/O pack to the IS200SDII terminal board.
• Add a WDII option board when system wetting is required.
• Verify the channel fuse is present before enabling system wetting.
• Check the JE1 or JE2 polarity before applying wetting voltage.
• Confirm the operating temperature stays within -30 to 65°C.
