Safety

Maximum Voltage^[1]

Connect only the voltages that are within these limits.

Port-to-COM

-27 VDC to +40 VDC max, Measurement Category I

Measurement Category I is for measurement performed on circuits not directly connected to the electrical distribution system referred to as MAINS voltage. MAINS is a hazardous live electrical supply system that powers equipment. This category is for measurements of voltages from specially protected secondary circuits. Such voltage measurements include signal levels, special equipment, limited-energy parts of equipment, circuits powered by regulated low-voltage sources, and electronics.

Caution

Do not connect to signals or use for measurements within Measurement Categories II, III, or IV.

Note

Measurement Categories CAT I and CAT O (Other) are equivalent. These test and measurement circuits are not intended for direct connection to the MAINs building installations of Measurement Categories CAT II, CAT III, and CAT IV.

Isolation Voltage

Port-to-earth ground
Continuous	60 VDC, Measurement Category I

Note

The TRC-8542 COM signals are not connected to the host port ground.

Environmental

Refer to the manual for the host you are using for more information about meeting these specifications.
