The TXM1.8D and TXM1.16D are dedicated to monitoring, respectively, 8 and 16
digital input points.
They monitor status signals from normally open (NO) or normally closed (NC),
latched voltage free/dry contacts.
All 8 points on the TXM1.8D module as well as 8 of the 16 points on the TXM1.16D
module may be used as pulse counters up to 10 Hz.
Each input point has a green LED for status indication.
NOTE:
Potential free (dry contact) for all points.
