Siemens 6ES7193-0CA10-0XA0 spare-part terminal block for SIMATIC DP, for digital submodules with 3-wire screw connections. Operates at 24 V DC, supply range 18.5–30 V including ripple, max 170 mA (typ. 100 mA). Width 160 mm, depth 59 mm, height 130 mm.
Key ratings and what they mean for fit
The supply tolerance of 18.5–30 V DC inclusive of ripple allows this terminal block to work on industrial 24 V buses with moderate sag or ripple, common in older or long-run DC systems. The 170 mA maximum consumption counts toward the backplane power budget—if populating multiple TB1 blocks, tally the total to stay within the bus power limit. Temperature range of 0 to 60 °C fits standard indoor cabinet conditions; no derating needed for most plant-floor environments. For applications near ovens or in unventilated enclosures, confirm the ambient stays under 60 °C.
Connection design
This terminal block offers two connector IDs on the same body: TB1 uses screw terminals (traditional and field-reliable), while TB3 gives spring-cage terminals (faster termination, vibration-resistant). Having both on one block means you choose the wiring method per the cabinet standard without sourcing a different variant. The electrical connection between the electronic block and PROFIBUS DP is included.
