Both modules are PROFIBUS-DP interface devices with "4-channel digital output+8-channel digital input". The core difference lies in the explosion-proof level of the output terminal. The specific comparison is as follows:
Comparison item model 07-7331-2305/000 model 07-7331-2305/1000
Output explosion-proof level Ex e (increased safety type) Ex i (intrinsic safety type)
Output voltage U2-0.2V (approximately 23.8V when U2 is 24V) DC 22V (when U2 ≥ 24V)
Single channel maximum output current 500mA-
Single channel internal resistance -301 Ω
Module loss power maximum 3.5W maximum 4.5W
Control object: 4-channel Ex e valve, 4-channel Ex i valve
