ZA 57630
21 to 25
IN
EXT_COM
External DC power input (common)
Each signal of the handler interface is
isolated from the enclosure and operates with
external DC power.
41 to 45 OUT INT_DCV
Internal DC power output (+5 V)
46 to 50 OUT INT_COM
Internal DC power output (common)
This is connected to the enclosure. To operate
the handler interface by the internal DC
power source, connect between EXT COM and
INT COM and between EXT DCV and INT
DCV.
* (NU): Not used, unused signal. H level is always output.
* When /ERR output, other comparison result signals will not be output.
* The “/” at the beginning of the signal name indicates negative logic (1 at low level).
■ Signal specifications
External DC power
: Rated v5 to +24 V, operating range +4.5 to +26.4 V
Maximum current consumption 45 mA (5 V) / 100 mA (12 V) /
180 mA (24 V)
Internal DC power
: +5 V typ., 70 mA max., connected to the enclosure
Also output during standby.
Isolation
: 42 Vpk
(each signal, common) vs. enclosure
When the internal DC power output connector and the external
DC power input are connected, isolation is not provided.
Output Characteristics
Output low level : 0.5 V max. (power voltage 5 V, sink current 6 mA)
1.2 V max. (power voltage 12 V, sink current 8 mA)
2.4 V max. (power voltage 24 V, sink current 10 mA)
Output high level : 5 to 24 V (depends on the power voltage)
Input characteristics (excluding trigger)
Input low level
: (Power voltage
–
4.1 V) max.
Input high level : (Power voltage
–
1.1 V) min.
Input characteristics (trigger)
Input low level
: (Power voltage × 0.3 V) max.
Input high level : (Power voltage × 0.7 V) min.
Connector
: DDK 57 series 50-pin or equivalent
!
WARNING
Do not apply a voltage more than 42 Vpk between the signals or common of the handler
interface and the enclosure. There is a risk of an electric shock.
