Compact Analog Output Standby Manual device
The compact Analog Output Standby Manual (AOSM) device display panel, as shown in the following
figure, monitors the outputs of an Analog Output (AO) IOP as well as the AOSM itself, presenting their
output values on the display panel as a percentage of the range. It can be ordered by Honeywell part
number 51401926-100.

Features
The Analog Output Standby Manual device has the following features.

The Analog Output Standby Manual device will accept the standard IOP to FTA cables with either
DIN or phone type connectors.

The Analog Output Standby Manual device can be powered by any of two methods.

The HPM card file backpanel through its connection to the STANDBY MANUAL connector on
the FTA.

By applying 110 or 220 Vac to connector at the side of the AOSM. The universal power supply
in the AOSM will accept 100 to 240 Vac, 50/60 Hz.

The panel display shows the 4-20 milliamp current levels in a 0% to 100% scale for all eight IOP
outputs as well as the level of all eight AOSM outputs.

The toggle switches are a “tamper-proof” style that require the operator to lift up on the bat handle
before changing the switch position.

The compact AOSM’s output current and the its
OUTPUT SOURCE SELECT switches are
disabled when the device is first connected to the FTA, the
STANDBY ENABLE
indicator is
extinguished, or the cable to the FTA is disconnected.

When the AOSM is enabled by depressing the STANDBY ENABLE switch, the STANDBY
ENABLE
indicator is illuminated and the
OUTPUT SOURCE SELECT
switch settings are
active.

The balancing of the AOSM output values to equal the IOP output values is performed
automatically, either continuously, or by single snapshot action. Balancing in the other direction,
IOP to AOSM, is an operator function.

A
DIR/REV
switch for each channel flips the display and reverses the
INC/DEC
action relative to
the actual current level. In the DIR position, 4 mA equals 0% and 20 mA equals 100%. The INC
position of the
INC/DEC
switch will increase current and the
DEC
position will decrease current.
