SAO-0220m Safe Analog Output Module

Overview: The SAO-0220m safe analog output module furnishes two channels of 0(4)-20 mA output, catering to analog control requirements. It boasts galvanic isolation from the 24 V DC and 5 V DC supplies for enhanced safety.

Features:

• Output Channels: Two channels of 0(4)-20 mA output, compatible with resistive or capacitive loads.
• Galvanic Isolation: Ensures outputs are insulated from supply voltages, guaranteeing safety and preventing interference.
• Secondary Means of De-energizing (SMOD): Each output incorporates a secondary means of de-energizing, enabling independent deactivation by the watchdog and processor irrespective of application status.
• Diagnostic Testing: Regular testing of analog outputs for correct output value, de-energization capability, and crosstalk between channels.

Technical Specifications:

• Type Numbers: FS-SAO-0220m, FC-SAO-0220m, compliant with international safety standards.
• Approvals: CE, TUV, UL, CSA, FM, indicating compliance with regulatory requirements.
