Remote I/O R3 Series

DC VOLTAGE INPUT ALARM MODULE
(4 points, isolated)

MODEL: R3–AV4[1][2]

ORDERING INFORMATION
• Code number: R3-AV4[1][2]
Specify a code from below for each of [1] and [2].
  (e.g. R3-AV4W/CE/Q)
• Specify the specification for option code /Q
  (e.g. /C01)

NO. OF CHANNELS
4: 4

[1] COMMUNICATION MODE
S: Single
W: Dual

[2] OPTIONS (multiple selections)
Standards & Approvals
blank: Without CE
/CE: CE marking
Other Options
blank: none
/Q: Option other than the above (specify the specification)

SPECIFICATIONS OF OPTION: Q
COATING (For the detail, refer to M-System's web site.)
/C01: Silicone coating
/C02: Polyurethane coating
/C03: Rubber coating

CAUTION
UNUSED INPUT CHANNELS
Set the unused channels to the ranges other than 1 - 5 V. Otherwise, set them as "Unused" with PC Configurator software: R3CON. Unused channels left open with 1 – 5 V setting are equal to the input lower than -15 %, which sets a data abnormality at the PLC or the host device.
Open circuit with the input range set to ±10 V means 50 % of the full-scale. An alarm setpoint must be set to a value that does not trip an unwanted alarm.

ALARM SETTING
The following parameters are programmable using the PC Configurator Software (model: R3CON).
ALARM TRIP POINT (-15.00 to +115.00 %;
factory set to A1: 80.00, A2: 60.00, A3: 40.00, A4: 20.00)
Four alarm setpoints are selectable per each input.
ALARM TYPE
(High or Low; factory set to A1: High, A2: High, A3: Low,
A4: Low)
High or Low alarm is selectable for each alarm trip point.
High alarm: An alarm is set when the input signal goes above the setpoint.
Low alarm: An alarm is set when the input signal goes below the setpoint.
DEADBAND (HYSTERESIS)
(0.00 to 100.00 %; factory set to 5.00)
Deadband (deviation between the points where the alarm is set and reset) is selectable for each alarm trip point.
ALARM ON DELAY TIME
(0.0 to 99.0 seconds; factory set to 1.0)
The alarm output is set when the preset time elapses after the input has entered in the alarm range.
This setting is common to all four points.
POWER ON DELAY TIME
(0.0 to 99.0 sec.; factory set to 5.0)
The alarm output start functioning in the preset time after the power has been turned on.
This setting is common to all four points.
ALARM HOLD TIME
(0.0 to 99.0 seconds; factory set to 1.0)
The alarm output is held for the preset time even if it is reset in shorter time.
This setting is common to all four points.

EXTERNAL VIEW

OUTPUT DATA DESCRIPTIONS
Four alarm setpoints are selectable per each input. One (1) word (16 bit) data is transmitterd to the PLC or the host device via the R3 network module.
