Main technical features of PDM-04XAM system:

analog input quantities: 12 channels (configurable currents and voltages, Input current = 1 or 5 A AC, Input voltage = 60 or 100 V AC); 12-bit resolution;
binary input quantities: 24 channels;
input sampling frequency: 1000 Hz;
supply voltage: 220 V DC or AC;
recording triggering: transition of binary inputs (programmable), exceeding of analog input thresholds (programmable), by another PDM-type device, manually;
recording time: maximum recording time approx. 350 sec; programmable pre-alarm, alarm, and post-alarm time;
real-time clock;
proper operation self-testing and fault status signaling;
serial communication line for long-distance data transfer, current loop, RS485 1 km maximum), optical fiber, 57600 baud;
RS232 serial line for local communication, by connecting a portable computing device;
event synchronization line for multiple PDM-type units;
ON-LINE operation and the possibility of configuring multiple PDM-type units into a distributed monitoring and recording system;
synchronization line for analog signal acquisition;
communication, analysis, and management software;
overall dimensions of approximately 320/170/100mm;
approx. weight of 1.9 kg;
easy mechanical and electrical installation at the location where the electrical quantities will be acquired.
