Technical data
Test outputs (X1, X2)
Number of outputs 2 (with 2 test pulse generators)
Output type PNP semiconductor, short-circuit protected, short-
circuit monitoring (selectable)
Output voltage High
15 … 30 V DC (max. 1.8 V drop to terminal A1 of
CPU module)
Output resistance Low ≤ 33 Ω ± 10 %, current limited at approx. 10 mA
Output current Max. 120 mA at each test output (X1 or X2)
This means that a maximum of 8 testable sensor
cascades per module with max. 30 mA each are
possible.
The total current for the MELSEC-WS safety
controller for all outputs (X1…X8 and XY1…XY2) is
limited to a maximum of 1.28 A. This corresponds to
e.g. a maximum of 32 testable sensor cascades with
30 mA each plus 64 tactile sensors on inputs on
safety I/O modules with 5 mA each.
Test pulse rate (test period) 1 … 25 Hz, configurable
Test pulse duration (test gap) 1 … 100 ms, configurable
Load capacity 1 μ F for test gap ≥ 4 ms
0.5 μ F for test gap 1 ms
Cable resistance < 100 Ω
Safe outputs (Q1 … Q4)
Number of outputs 4
Output type PNP semiconductor, short-circuit protected, short-
circuit monitoring (selectable)
Output voltage High 16 … 30 V DC (max. 0.8 V drop to terminal A1 of
this module)
Leakage current Low
