Display

Upper : 4 digit, 0.56" (13 mm), 7 - Segment RED L.E.D display for 'Process Value' indication
Lower : 4 digit, 0.56" (13 mm), 7 - Segment RED L.E.D display for 'Set Point Value' indication of RL1

L.E.D. Indication

RL1 & RL2 for Relays, TX & RX for communication
PRG to show 'User' in Programming mode & O/P to show 4 - 20 mA O/P is selected instead of the Relay 2

Set point

Independent set points setting for RL1 & RL2

Hysteresis

1 To 100 counts, Independent setting for RL1 & RL2

Control action

LO -HI, HI-LO, LO- Very LO, HI - Very HI control action for relay; programmable by user

Time delay

0 To 9999 sec, Common setting for RL1 & RL2 to operate after the 'Process Value' crosses the 'Set Point Value'

Relay contact type

1 NO - C - NC Relay Contact Rated 230 VAC/5A for RL1 & RL2

Configuration of relay

RL1 operates for Set point 1, RL2 operates for Set point 2 ( RL2 is optional)

Fault condition

In 'Under', 'Over' OR 'Open' condition i.e. fault condition, Relay can be made OFF or ON; programmable by user

Setting

Setting by 4 keys on front panel i.e. 'SET / NEXT', 'UP' , 'DOWN' & 'BACK'

Monitoring : Sensor

Open / Under / Over

i) By Display : Sensor 'Break/ Open' shows 'oPEn', 'Under' range shows 'Undr' & 'Over' range shows 'ouEr'
ii) By Retransmission current O/P : Up scale current : 21 mA, Down scale current : 3 mA; programmable by user

Retransmission output

(Optional)

i) 1 No. 4 - 20 mA output with MAX Load 750 ohms
ii) Range: As per the Input type, Low range / High range: Anywhere in the range (High range > Low range)
