ABB pneumatic component V18345-1010261001 position positioner

Description

V18345-1010261001 Four D/A converters provide simultaneous current and voltage outputs from each output channel.

Current output spans are 0-20 or 4-20 mA; voltage spans are 0-10 or 0-12.5 volts. All outputs are

isolated from ground and logic, but are grouped on a common V18345-1010261001 power supply. Outputs can be

isolated as a group from the rest of the system if a separate isolated loop supply is used.

V18345-1010261001 Each circuit provides simultaneous voltage and current outputs from the digital to analog converter.

All circuits share a common loop supply and return.

The current driver is a sourcing type. The low side of a load can be connected to RET, the negative

side of a 24 V loop supply, or a more negative point that can be up to 36 volts negative with respect

to the module 24 volt supply positive terminal.

Voltage output is relative to RET terminal, V18345-1010261001 which is common to all circuits. The module’s 10 ohm

resistor helps reduce ground loop circulating currents.

The operating range for an output can be changed to 0-20 mA, 0-12.5 volt by connecting the JMP

terminal to the RET terminal for that output.

V18345-1010261001 The module contains MOV transient voltage suppressors, and RF bypass capacitors to the module

chassis. The chassis point is connected to the module case and the chassis ground terminal on the

module base. This should be grounded for best noise immunity.

Outputs default to minimum value upon initial powerup or loss of backplane power.

note 1: May limit or become non-linear below minimum values given, due to saturation of output drivers.

note 2: Minimum load should be 250 ohms if ambient exceeds 50deg. C. Valid over rated 18-30 supply

voltage. Maximum load can be increased to 800 ohms if min. supply voltage is greater than 23.0 volts,

including ripple.

note 3: Open wire occurs when there is insufficient compliance voltage to drive output to commanded value.

Therefore occurrence of open wire depends on combination of output load and current. The open wire warning

may occur continuously on a disconnected output, such as not used, or voltage used instead.

note 4: In the presence of severe RF interference (IEC 801-3, 10V/m), accuracy may be degraded to 1mA or

0.5V.
