Retransmission Output
Outputs the PV value.
Either the retransmission output or the loop power supply can be used with terminals
14
-
15
.
• Number of outputs: 1 (terminals
14
-
15
)
• Output signal: 4-20 mA DC
• Load resistance: 600 or less
• Output accuracy: 0.3% of span under standard operating conditions (232C,
5510% RH, power frequency of 50/60 Hz)
Contact Inputs
• Purpose: Resetting of PV peak and bottom values
• Number of inputs: 1
• Input type: Non-voltage contact or transistor open collector input
• Input contact rating: 12 V DC, 10 mA or more
• On/off determination: For non-voltage contact input, contact resistance of 1 k or less
is determined as “on” and contact resistance of 20 k or more as “off.”
For transistor open collector input, input voltage of 2 V or less is determined as “on”
and leakage current must not exceed 100 A when “off.”
• Minimum status detection hold time: About 1 second
Contact Outputs
• Purpose: Alarm output, FAIL output, and others
• Number of outputs: 4 (Max).
• Relay contact rating for Alarm 1 to 3: 240 V AC, 1 A, or 30 V DC, 1 A; 1a
• Relay contact rating for Alarm 4: 250 V AC, 3 A, or 30 V DC, 3 A (resistance load)
3 terminals (NC, NO, Common); 1c
Display Specifications
• PV display: 4-digit, 7-segment red LED display, character height of 20 mm (for both
UM350 and UM330)
• Setpoint display: 4-digit, 7-segment, red LEDs, character height of 9.3 mm (for both
UM350 and UM330)
• Status indicating lamps: LEDs
