Rated power
supply voltage |
12 to 24 VDC (Allowable voltage fluctuation range: 10 to 30 VDC) |
Operate
resistance |
0 Ω to 50 MΩ, variable
Range 0: 0 to 250 kΩ. Range 1: 0 to 600 kΩ
Range 2: 0 to 5 kΩ. Range 3: 0 to 50 kΩ
Note:
The range is set using the DIP switch on the side of the Sensor Amplifier. (Refer to DIP
Switch Settings.) Set the corresponding pin of the DIP switch in the up position.
(For range 0, set all 3 pins in the down position.) The adjuster (ADJUST) on the top of
the Sensor Amplifier sets the resistance value for detection within the set range. It is
factory-set to the upper limit. (Normally, the K7L can be used with the adjuster at this
setting.)
With any range, resistance values can be set from 0 Ω. |
Disconnection
detection
function * |
Detection signal: 10 VDC max., 200 ms
Detection time: 10 s max.
Recovery: Operation is recovered by resetting the power supply. |
Release resistance |
105% min. of operate resistance |
Output
configuration |
NPN open-collector transistor output with 100 mA at 30 VDC max. for both liquid leakage
detection and disconnection detection.
Max. 30 VDC, 100mA
Note:
If the rightmost pin of the DIP switch on the side of the Sensor Amplifier is set to the
down position, the output turns ON when liquid is detected; if it is set to the up position,
the output turns OFF when liquid is detected. |
Wiring distance |
Connecting cable: 50 m max.
Sensing Band length: 10 m max.
Note:
These values are possible on condition that a completely insulated 3-conductor VCT
cable with a thickness of 0.75 mm2 and a dielectric strength of 600 V is used
together with a Liquid Sensing Band specified by OMRON. (A 0.2-mm2 cable can
also be used.) |
