ABB S800 I/O Modules and Termination Units

The DO815 Digital Output Module has 8 channels, 24 volt d.c., 2 A, digital outputs.

The outputs are divided into two isolated groups of four channels with a voltage

supervision input for each group. Each output channel provides protection against

short circuits to ground, over-temperature, EMC protection, output state LED

indicator and optical isolation from the ModuleBus. State of outputs can be set to a

predetermined (OSP) value if a communications lost error is detected.

DO818 Digital Output Module, 24 V, 0.5 A, Current Sinking

The DO818 Digital Output Module has 32 channels for 24 volt d.c., 0.5 A, digital

outputs. The outputs are divided into two isolated groups of 16 channels with a

voltage supervision input for each group. Each output channel provides protection

against short circuits to ground, over-voltage, over-temperature, EMC protection,

output state LED indicator and optical isolation from the ModuleBus. State of

outputs can be set to a predetermined (OSP) value if a communications lost error is

detected.

DO820 Digital Output Module, Relay Normally Open

The DO820 Digital Output Module has 8 channels for 230 volt a.c./d.c. relay

outputs. The outputs are individually isolated. Each output channel provides a relay

contact (NO - Normal Open), EMC protection, output state LED indicator and

optical isolation from the ModuleBus. State of outputs can be set to a predetermined

(OSP) value if a communications lost error is detected. Internal voltage is

supervised.

DO821 Digital Output Module, Relay Normally Closed

The DO821 Digital Output Module has 8 channels for 230 volt a.c./d.c. relay

outputs. The outputs are individually isolated. Each output channel provides a relay

contact (NC - Normal Closed), EMC protection, output state LED indicator and

optical isolation from the ModuleBus. State of outputs can be set to a predetermined

(OSP) value if a communications lost error is detected. Internal voltage is

supervised.

DO828 Digital Output Module, Relay Normally Open

The DO828 Digital Output Module has 16 channels for 250 AC / 125V DC relay

outputs. The outputs are individually isolated. Each output channel provides a relay

contact (NO - Normal Open), EMC protection, output state LED indicator and

optical isolation from the ModuleBus. State of outputs can be set to a predetermined

(OSP) value if a communications lost error is detected. Internal voltage is

supervised.

The DO840 Digital Output Module has 16 channels for 24 V d.c. The maximum

continuos output current is 0.5 A. The module has advanced on-board diagnostics. It

can be used in both single and redundant applications.

DO880 High Integrity Digital Output Module, for Single or Redundant Configuration

The DO880 High Integrity Digital Output Module is TÜV certified for

IEC 61508 SIL3 and EN 954-1 Category 4.

The DO880 has 16 channels for 24 V d.c. The maximum continuous output current

is 0.5 A. The module has advanced on-board diagnostics. It can be used in both

single and redundant configuration.

DP820 Incremental Pulse Counter Module

DP820 is an two-channel pulse counting module for incremental pulse transmitters

up to 1.5 MHz. Each channel contains counters and registers for position/length and

speed/frequency measurement. Each channel provides three balanced inputs for

connection of a pulse transmitter, one digital input and one digital output.

Pulse transmitters with RS422, +5 V, +12 V, +24 V and 13 mA interfaces can be

connected to DP820.

DP840 Incremental Pulse Counter Module, for Single or Redundant Applications

DP840 has 8 channels and each channel can be configured for pulse count or

frequency measurement. The maximum frequency of input signals is 20 kHz. The

inputs can also be read as digital input signals.

Input signal range NAMUR, 12 V and 24 V.

S800L I/O Modules

The I/O modules have open ventilated plastic enclosures and a bottom of sheet

metal. On the front of each I/O module there is one LED (STATUS) indicating the

module status and digital I/O modules have one status LED for each channel. Refer

to Hardware Indicators on page 47 for the status indication of the LEDs.
