TEK.COM34
The 7707 plug-in module offers 10 channels of 2-pole or 5 channels
of 4-pole multiplexer switching that can be configured as two
independent banks of multiplexers. The 7707 also provides 32 digital
input/output channels (four 8-bit ports) for I/O control. Connect the
7707 to industry standard solid-state relays to switch up to 980 VA.
Key Features
• 300 V, 1 A capacity; 60 W, 125 VA maximum (analog)
• 33 V, 100 mA capacity (digital)
• Digital outputs are short circuit protected
• Relay closures stored in onboard memory
