Siemens 6ES7193-6BP00-0DA0 SIMATIC ET 200SP Base Unit

Product Overview

The Siemens 6ES7193-6BP00-0DA0 is a BaseUnit BU15-P16+A0+2D (BU Type A0) for the SIMATIC ET 200SP distributed I/O system. As a dark BaseUnit, it opens a new load-voltage (potential) group and supplies the I/O module plugged onto it. It features 16 push-in process terminals for field wiring and is designed for compact, high-density panel layouts.

Features & Benefits

• Compact 15 mm width — enables high-density I/O configurations, reducing panel footprint by up to 60% compared to legacy 40 mm+ base units
• Push-in terminal technology — tool-free wiring with IEC 60947-7-1 compliance, vibration-resistant for automotive and heavy-industry environments
• New potential group starter — isolates power distribution for the module stack, improving fault isolation and diagnostics
• No auxiliary terminals — cost-optimized for simple I/O systems where cross-module bridging is unnecessary
• Compatible with Type A0 and A1 I/O modules — digital inputs, digital outputs, analog I/O, and combination modules

Typical Applications

• Automotive assembly line distributed I/O nodes
• Food & beverage packaging and conveyor controls
• Pharmaceutical batch processing skids
• Machine builder OEM platforms with standardized ET 200SP architecture
• Brownfield retrofit projects adding decentralized I/O capacity
• HVAC and building management system (BMS) valve/damper control

Installation Guide

1. Verify compatibility — confirm your carrier rail is ET 200SP standard; do not mix with ET 200S or older SIMATIC series hardware.
2. Mount on de-energized DIN rail — slide the BaseUnit horizontally onto the ET 200SP carrier rail until an audible click confirms full seating.
3. Install external protection — place a 24 V DC / 10 A miniature circuit breaker (Type B or C) upstream of the L+ supply; this BaseUnit has no internal breaker.
4. Wire field devices — use conductors within 0.14–2.5 mm² range; insert into push-in terminals until the audible click is heard.
5. Perform tug-test and continuity check — gently pull each wire and verify with a multimeter before applying power.
6. Install I/O module — seat the compatible ET 200SP Type A0/A1 module onto the BaseUnit backplane.

FAQ

Q: What is the difference between 6BP00-0DA0 and 6BP20-0DA0?
A: The 6BP00-0DA0 has no auxiliary terminals (A0), while the 6BP20-0DA0 includes 10 auxiliary terminals (A10) for cross-module signal continuity. Both open a new potential group (2D). Choose 6BP00 for cost-sensitive, simple I/O builds; choose 6BP20 when auxiliary bridging is required.

Q: Is this BaseUnit compatible with ET 200S modules?
A: No. ET 200SP and ET 200S use incompatible backplane standards. Mixing them will cause physical seating failure and electrical damage. Verify all modules carry the ET 200SP family designation.

Q: Does this BaseUnit have built-in circuit protection?
A: No. An external upstream 24 V DC protection device is mandatory. Omitting it risks catastrophic failure of connected I/O modules during a surge or short circuit.

Q: What conductor gauges are supported?
A: Push-in terminals accept solid or flexible conductors from 0.14 mm² to 2.5 mm². Using oversized conductors will damage terminal contacts irreparably.

Q: Can I use this BaseUnit with Type A1 I/O modules?
A: Yes. BU Type A0 BaseUnits accept both Type A0 and Type A1 ET 200SP I/O modules.

Selection Tips

• Choose the 6BP00-0DA0 when your system has no auxiliary power requirements and you want the lowest-cost BaseUnit for a new potential group.
• If your I/O module set includes analog modules or modules requiring auxiliary current, upgrade to the A10 variant (6BP20-0DA0) for dedicated 10 A auxiliary capacity.
• If your control logic requires isolated power groups (e.g., safety circuits or mixed-potential field devices), select the 2B variant (6BP20-0BA0) instead of 2D.
• Always verify the exact part number character-by-character against your BOM — 6BP00 vs. 6BP20 and 0BA0 vs. 0DA0 differ by only a few characters but represent entirely different configurations.
